The line graph given below shows the percentage distribution of literate population of each city out of total population of each city of five different cities.

Note:

  1. Sum of literate and illiterate population of city B is 5000.
  2. Population of city A is 25000 less than the population of city E Population of city D is 20000 more than the population of city C Ratio of population of city E and C is 4:1. Average population of city E and C is 25000.

Ques : What is the average of the total population of all the cities together?

Correct Answer: (e) 20000

Total population of city E and C = 50000
Population of city E = (4/5) × 50000 = 40000
Population of city C = 50000 - 40000 = 10000
Population of city A = 40000 - 25000 = 15000
Population of city D = 10000 + 20000 = 30000

City

Literate population

Illiterate population

A

(40/100) × 15000 = 6000

(60/100) × 15000 = 9000

B

(20/100) × 5000 = 1000

(80/100) × 5000 = 4000

C

(50/100) × 10000 = 5000

(50/100) × 10000 = 5000

D

(60/100) × 30000 = 18000

(40/100) × 30000 = 12000

E

(50/100) × 40000 = 20000

(50/100) × 40000 = 20000

Required average
= (15000 + 5000 + 10000 + 30000 + 40000)/5
